How To Unclog The Condensation Drain Line Of AC Unit

Is your air conditioner not working? Check the air conditioning unit for standing water, a drain pan full of water, a moldy smell, or water damage. These are telltale signs that your condensation drain line is clogged. To unclog the condensation drain line of your AC unit, follow these steps:

  • Step 1 – Turn off the power to your AC unit. This is done by turning the system off at your thermostat.
  • Step 2 – Find the end of your AC drain line (typically a pipe on the exterior of your home) and use a thin-wired brush to unclog and clean
  • Step 3 – Attach the end of a wet/dry vacuum to the end of the AC drain line. Seal it securely using duct tape and turn the vacuum on to remove debris or clogs. Remove the vacuum and tape.
  • Step 4 – Go inside and locate the vent tee. This is a pipe fitting that connects your AC drain line to the drainage tray. Remove the PVC cap from the top of the vent tee and clean inside with a brush to clear out any clogs.
  • Step 5 – Pour a mixture of one cup bleach and one cup water into the vent tee entrance, waiting thirty minutes.
  • Step 6 – Place a bucket at the end of the drain line, then pour water into the vent tee, and head outside to see if it made it all the way through the AC drain line.

Keeping Cool Without Air Conditioning

A/C not working? It’s still important to stay cool while you wait for a fix. Here are some quick tips:

  • Turn on fans. Ceiling fans and floor fans are a great way to keep cool air breezing through your home – and much more energy-efficient than A/C
  • Create a cross-breeze. If the weather is not too hot, opening up at least two windows in your house, thereby creating a cross-breeze, can help keep it cool throughout your home.
  • Get wet. Use cold washrags on your neck and/or wrists to keep cool while you wait. You can also take a cool shower or bath to soothe your body.
